how to check for the number os spaces in a line of words?

wad code must i use?

is it isspace()?

well there is no hardcoded way.

so just think like this. Space is also a character ' '. so you can count that
character.

text = "This is my line" ;
int count = 0;
for (int i = 0; i < text.size(); ++i)
if (text[i] == ' ')
++count;

// the count contains number of spaces. 

[sanzilla]

if you are using the STL the things are even easiear more
than that.

std::count(text.begin(), text.end(), ' ')

[Gumbercules]

Pointers to a cstring can be used in place of those iterators too.
and you need to #include <algorithm> for std::count.

Also

std::count_if( text.begin(), text.end(), isspace )

if by "space" you also mean hard spaces, tabs, and/or newlines.
